I believe your approach is the right one.
It would be interesting to see how much of a performance gain
is seen with real applications, though from hugetlbfs experience
we already know that some applications can see significant
performance gains from using large pages.
As for the code - this patch is a little too big to comment
on all the details individually, but most of the code looks
good.
It would be nice if some of the code duplication with hugetlbfs
could be removed and the patch could be turned into a series of
more reasonably sized patches before a merge.
